So 1 billion dollars buys about 8 billion gloves? Or about 4 weeks? So for 12 billion dollars that's a years slack?
I am not sure what you are getting at, continuously spending money on cost ineffective gloves just in case there is a problem sometime, including the upfront investment.
The scale of the storage? We have 6000 hospitals in the US. which would have to store about 2 million gloves a piece if you decentralized it. The storage space would be about 2 10x10x10 cubes in each location, probably varying dramatically by hospital size. Of course that is just proper hospitals, we have many many more medical facilities that use them. I don't see storage being a problem.
So what is the scale we are talking here? A complete 6 month supply would be half the cost, which still seems excessive. And this is a pandemic scenario we are talking about that uses a lot of gloves, not a national security concern where we would not have that much additional use.
